Analytical simulation of statistically inhomogenous intensity fluctuations of biospeckles using band-limited fractal model

摘要

Analytical simulation model for description of speckle intensity fluctuations which is based on the one-dimensional band-limited Weierstrass function, is discussed. Certain 'non-linearity' as the dependence of Weierstrass function parameter on its argument is introduced to simulate large- scale inhomogeneities. Reconstruction of scattering structures images on the basis of speckle correlometric technique is studied using the developed model.
